@dipeshgupta197 your code misses the case like
aabbbbbaabbbb where k=2
we try to change a here and the string becomes bbbbbbbaabbbb and if we uses the k=2 moves in the aa which are later then it becomes aabbbbbbbbbbb which is more good for us so this approach is not good
instead we can use 2 pointer approach
Coding Blocks IDE
this is the complete explanation if your dout is not still clear let me know and if clear mark it resolved
